1. APPLICATION
The NIVOCONT vibrating rod level switches are suitable for low and high level indication of granules and powders with a
3
min. 0.05 kg/dm density such as cement, lime, sand, grain, feed, sugar, etc. Dust Ex versions are available for using the
instrument in explosion-proof environment.
